To approach this problem, a computed torque controller integrated with a radial basis function neural network is proposed to achieve the high-precision vibration control for MLRS.
Particular challenges that have to be addressed are positioning with nanometer precision, motion control with high speeds and high precision, and vibration isolation to counteract environmental disturbances.
In order to protect the high precision payloads from the vibration disturbances, vibration isolators are often applied in the vibration propagation path.
The Middeck Active Control Experiment $̄Flight II (MACE II) is a space shuttle flight experiment designed to investigate modeling and control issues for achieving high precision pointing and vibration control of future spacecraft.
For high-speed robotics dynamic (shaking) force and (shaking) moment balance are important properties to obtain low base vibrations, high precision, and short cycle times, a.o., while for large moving structures such as movable bridges and movable roofs force balance is important for safety and low energy usage.
The incubator system was equipped with a Nikon inverted microscope (TE2000-E, Nikon, Tokyo), which incorporates a high precision motorized-focus and vibration-free optical path changeover mechanism that facilitates image capture in 3D.
It is demonstrated that the DTM has high precision and computational efficiency in the vibration analysis of FG nanobeams.
Giant magnetostrictive actuators (GMA) used in vibration control and high precision positioning control have been studied widely in last decade.
While piezoelectric actuators have been widely used in vibration suppression and high precision controls, their intrinsic nonlinearity such as hysteresis, if not considered in control design, may deteriorate the system performance.
Active vibration isolation is gaining increased attention in the ultra high precision applications to effectively treat the unavoidable ground vibration.
Active vibration isolation against low-frequency ground tilt is important for detection of gravitational wave, however until now few low-frequency ground tilt detection and vibration isolation systems with high precision have been reported.
